Description

The present invention relates to a sliding door device comprising a wall element, a guide profile, a rolling carriage which is fixed to the wall element, which is rollably installed in the guide profile and which comprises a hook member, with which the wall member is slidable with respect to the guide profile, between a first end position and a second end position, and comprising a door stop for holding in a position d end of the wall member of the sliding door, wherein said door stop comprises a fixing body which can be fixed in the guide profile for fixing the door stop in the guide profile, wherein the door stop comprises a retaining element which is fastened to the fixing body for holding the rolling element hook element in an end position of the wall arrangement, wherein the door stop comprises adjusting means for adjusting the position of this retaining element relative to the fixing body and wherein the door stop comprises guide elements for guiding the adjustment movement. Sliding door device door stops with a rolling trolley without hook element, which can be held by these door stops in an end position - such as for example the sliding door device according to US 2006/0277850 A1 - are not very compact. The clamping by which the wall element is held in its end position is also not so effective in such sliding door devices.

Sliding door devices to which the invention relates include a rolling cart with a hook member, which can be secured by its door stop. The door stop in such sliding door devices can be of a more compact construction and provides for more effective clamping of the wall element into its end position, since the door stop can immobilize the door. hook element in this end position.

Similar sliding door devices are already described for example in EP 1 080 290 B1 and CH 657 415 A5. In the door stop of the sliding door device described in EP 1 080 290 B1, an elastic retaining member is part of the fixing body and the preload of the elastic retaining member is adjustable by means of a set screw. In the document CH 657 415 A5, a separate elastic element as a retaining element is likewise connected at one end to the fixing body and at its other end it is movable by means of a set screw with respect to the fixing element.

A great advantage of such a possibility of adjusting the position of the retainer relative to the fastener body is that the same door stop can be employed for sliding door devices having different types of wall elements. For heavier wall elements, the retaining element must in particular be in another position in order to be able to exert an identical retaining force on the rolling element hook element than for lighter wall elements. A disadvantage of the possibility of adjusting these sliding door devices is however that, when adjusting the position of the retaining element, the retaining force may be suitable for different wall elements, but the restraint force is here each time changed. The object of the present invention is therefore to provide a sliding door device according to the preamble of the first claim, whose retention force of the stop member can be even better preserved in an identical manner when adjusting the the retaining element for other types of wall elements. This object of the invention is achieved by providing a sliding door device 30 comprising a wall element, a guide profile, a rolling carriage which is fixed to the wall element, which is rollably installed in the rail section. guide and which comprises a hook member, with which the wall member is slidable with respect to the guide profile, between a first end position and a second end position, and comprising a door stop for holding in an end position of the wall element of the sliding door, wherein said door stop comprises a fixing body which can be fixed in the guide profile for fixing the door stop in the guide profile wherein the door stop comprises a retaining member which is attached to the fastener body for holding a carriage member hook member in an end position of the wall member, wherein the door stop includes adjusting means for adjusting the position of this retaining member with respect to the fixing body, wherein the door stop comprises guiding elements for guiding the adjusting movement, wherein the retaining member is movable in a direction substantially along the height of the guide profile and substantially parallel to itself by means of the adjusting means, wherein the fixing body or retaining member comprises one or more guide grooves, wherein the retaining element or the fastener body comprises one or more corresponding guide elements, which are slidably disposed in the one or more of the corresponding guide grooves and wherein said one or more or a plurality of guiding grooves and / or said one or more of the guiding elements (s) are part of said guiding elements, in such a way that that the retaining element is, when adjusted, moved entirely relative to the fixing body and remains substantially unturned. The retaining element of a sliding door device is no longer attached to or is no longer part of the fastener body, but it can be moved parallel to itself with respect to this fastener body. In this way, this retainer is no longer rotated during its adjustment. This rotation ensured that, when adjusting the retaining element, this retaining element came to be placed at another angle with respect to the hook element of the trolley, for which the retaining force was acting in another direction on the hook element and was thereby modified. Since the retaining element according to the invention is now set parallel to itself, it is for example possible to always adjust the same retaining force for different types of wall elements by the displacement of the element. detention. A stop member with a fastener having a guide groove and a retainer with a corresponding guide member leads to simpler embodiments which are more simply attainable than a stop member with an element. retainer having a guide groove and a fastener with a corresponding guide groove.

More specifically, the door stop may further comprise as guiding elements of this type clamping screws for fixing in the clamping position of the fastener body in the guide profile, and the retaining element may have, as guiding elements of this type, perforations through which these clamping screws are freely arranged.

According to a preferred embodiment of a sliding door device according to the present invention, the guide profile is a substantially U-shaped profile, having a bottom and upright sides, and the fixing body comprises a profile portion substantially U-shaped, comprising a bottom and upright sides, wherein the bottom of the U-shaped profile portion extends, in the mounted state of the sliding door device, substantially parallel to the bottom of the guide profile. Each aforementioned guide groove is then preferably provided in an erected side of the substantially U-shaped profile portion of the fastener body. In addition, each guide groove preferably extends substantially perpendicular to the bottom of the U-shaped profile portion in the corresponding upright side. In a sliding door device in which the fixing body comprises such a U-shaped profile portion, this fixing body preferably comprises, on the side of the rolling carriage, a raised head side with respect to its bottom, on which there is provided a buffer element.

Further, when the fastener body comprises such a U-shaped profile portion, at least a portion of the retaining member preferably extends between the upstanding sides of the U-shaped profile portion and, when of the displacement of the retaining element by means of the adjusting elements, this part of the retaining element is moved parallel to the bottom of the U-shaped profile part between the erected sides of the shaped profile part. The retaining member of a fastener body according to the present invention preferably comprises a base body and one or more retaining legs extending relative to the base body, wherein each retaining leg has a abutment face against which the carriage slide hook member abuts upon movement of the wall member to the relevant end position, wherein each retaining leg has a sensibly connected retaining face at and at an angle to the abutment face, with which, when the wall element is in the relevant end position, the hook element is retained and in which, by abutment of the element of hook against the abutment face, overcoming the counterforce exerted by the retaining leg on the hook member, the hook member is brought into the end position from the side of the abutment face to the side of the retaining face and vice versa, during the abutment of the hook element against the retaining face, by overcoming the antagonistic force exerted by the retaining leg on the hook element, the hook element is brought out from the end position from the side of the retaining face to the side of the abutment face.

In a first specific embodiment of a sliding door device according to the present invention, the retaining element is made in the form of an elastic member in which said retaining force is an elastic force. With such an elastic element as a retaining element, this retaining element, seen in neutral position for which the elastic element is not under stress, is movable parallel to itself by means of adjustment means. Alternatively, the retaining member may also be embodied as a rigid member that is tiltably mounted, for which the counterforce is gravity or spring force of an additional spring, etc. When such a tilting element is provided as a retaining element, this retaining element, each time seen in a defined tilted position, is movable parallel to itself with the aid of the adjustment elements. Said at least one guide element of the retaining element of a sliding door device according to the present invention is preferably a portion oriented substantially perpendicular to the base body. The fastener body of a sliding door device according to the present invention is preferably folded from a metal plate. More preferably, this plate material is then executed as a stainless plate material. Alternatively, the fastener body and the retainer member of a sliding door device could be made of any other suitable material, such as a plastics material. A sliding door device according to the present invention further preferably comprises a set screw which is part of the adjusting means. In a particular embodiment of such a sliding door device, which comprises the two aforementioned clamping screws, the adjusting screw is placed between these two clamping screws. When the adjusting screw is placed between the clamping screws, the clamping screws can be better used as guiding elements for guiding the movement of the retaining element when moving it parallel to itself. The adjusting screw of a sliding door device comprising such a set screw is preferably fixed to the fastening body by being rotatable, being rotatable relative to this fastening body. This can be achieved by providing the adjusting screw, along its periphery, with a groove into which the plate material of a fastening body made of plate material engages. The present invention will now be explained in more detail with the aid of the following detailed description of a preferred embodiment of a sliding door device according to the present invention. The purpose of this description is only to provide illustrative examples and to reveal other advantages and features of this sliding door device, and therefore can in no way be interpreted as a limitation of the scope of application of the invention. invention or patent rights claimed in the claims. In this detailed description reference is made, by means of numerical references, to the accompanying drawings in which Figure 1 shows a door stop of a sliding door device according to the present invention, viewed in perspective; Figure 2 shows the door stop of Figure 1 in a side view; Figure 3 shows the fastener of the door stop of Figure 1, seen separately in perspective; Figure 4 shows the fastener of Figure 3 in the unfolded state; Figure 5 shows the retaining element of the door stop of Figure 1, seen separately in perspective; Figure 6 shows the retainer of Figure 5 in the unfolded state. In the figures, there is shown a door stop (1) of a sliding door device according to the present invention. Like the sliding door devices described for example in EP 1 080 290 B1 and CH 657 415 A5, such a sliding door device further comprises a wall element with which an opening in a wall can be closed. A guide profile of the sliding door device is for this purpose fixed to the wall on the upper side of this wall element. In this guide section, rolling carriages, on which there are several rollers each time, can roll in the guide section using these rollers. These trolleys are attached to this wall element on the upper side of the wall element, so that the wall element can slide with the aid of the trolleys relative to the guide profile between a first position of the wall element. end, wherein the door opening is open, and a second position in which the door opening is closed by means of the wall member. The illustrated door stop (1) is intended to be fixed in a guide profile, which is placed at the top of the sliding door device. For a person skilled in the art, however, it will be clear that a door stop (1) according to the present invention can also be used in sliding door devices comprising a guide profile which is installed at the bottom of the wall element, this the door stop (1) is then installed in this guide profile at the bottom of the sliding door device.

The wall element can be maintained in a known manner in an end position by means of the illustrated door stop (1), since a retaining element (3) of the door stop (1) maintains in this end position a hook member of a corresponding roller. For this purpose, the door stop (1) is fixed in the respective end position in the guide profile by means of a fastening body (2). The fastening body (2) of the illustrated door stop (1) can be fixed in the clamping position, in a known manner with the aid of two clamping screws (4), in the guide profile in order to fixing the door stop (1) in the guide profile.

The separate retaining element (3) of the illustrated door stop (1) is fixed to the fixing body (2) by means of a set screw (5). The retaining element (3) can be displaced by means of this adjustment screw (5) in a direction oriented substantially along the height of the guiding section substantially parallel to itself, relative to the fixing body ( 2). The adjusting screw (5) is for this purpose fastened to the fastening body (2) by virtue of the fact that it is provided at its periphery with a groove into which the fastening body (2) engages. On the other hand, the adjusting screw (5) is screwed in this way into a perforation (3e) in the retaining element (3). Both the fastening body (2) and the retaining element (3) of the illustrated door stop (1) are folded from a plate metal, as can be seen in FIGS. , in which this fixing body (2) and this retaining element (3) are represented in the folded state in perspective (FIGS. 3 and 5 respectively) and in the unfolded state (FIGS. 4 and 6 respectively) with their lines. folding. Such a door stop (1) can thus be produced in a particularly simple manner by stamping from a metal plate of the shapes shown in Figures 4 and 6 and folding of these forms along the fold lines shown until the shapes shown in perspective in Figures 3 and 5. A door stop (1) according to the invention could however, depending on the application, also be manufactured for example plastic or in any other imaginable manner.

The guide profile of the sliding door device according to the invention, wherein the illustrated door stop (1) is disposed, is a substantially U-shaped profile, comprising a bottom and upright sides. The fastening body (2) comprises a substantially U-shaped profile section (2a, 2b) corresponding to this substantially U-shaped profile, where the fastening body (2) is oriented with its bottom (2a) towards the bottom of the guide profile and is fixed in this guide section, substantially parallel to this bottom, using the clamping screws (4). On the side of the rolling carriage, the fixing body (2) further comprises a head side (2c) raised with respect to the bottom (2a), to which is fixed a buffer element (6). This buffer element (6) makes it possible, when the wall element is moved towards the end position concerned with a relatively high force, to absorb the impact of the rolling carriage against the door stop (1), such that the hook element can be retained by means of the retaining element (3) without being released immediately following the impact. As can be seen in Figure 1, at least a portion of the retaining element (3) extends between the upright sides (2b) of the U-shaped profile portion (2a, 2b) of the fastening body (2). When moving the retaining element (3) relative to the fastening body (2) by means of the adjusting screws (4), this part of the retaining element (3) always remains between the erected sides (2b) of the U-shaped profile portion (2a, 2b). In addition, the movement of the retaining element (3) relative to the fixing body (2) is further guided by additional guide means (4, 3d, 3c, 2d), so that the element of restraint (3) can always move as well as possible parallel to itself. The aforementioned clamping screws (4), with which the fastening body (2) is fixed in the guide profile, are freely inserted through perforations (3d) in the retaining element (3), and guide this the movement of the retaining element (3).

In each upright side (2b) of the fastening body (2) there is also a guide groove (2d), which extends substantially perpendicular to the bottom (2a) of the U-shaped profile portion (2a, 2b). ). In the retaining element (3), corresponding guiding elements (3c), which are slidably arranged in a corresponding guiding groove (2d), are provided for guiding the movement of the retaining element ( 3) when setting. The retaining element (3) of the illustrated door stop (1) comprises, in addition to these guiding elements (3c), a base body (3a) and two retaining legs (3b) extending compared to the basic body. In the base body (3a) are formed two perforations (3d, 3e), a perforation (3d) through which a clamping screw (4) is freely rotatably disposed, and a perforation (3e) in which the screw (5) is screwed in. The retaining legs (3b) delimit an additional perforation (3d), through which a clamping screw (4) is also rotatably disposed. The perforation (3e) for the adjusting screw (5) is made between the perforations (3d) for the clamping screws (4), so that these clamping screws can further guide the retaining element (3). ) during the adjusting movement of this retaining element (3). Each retaining leg (3b) of the retaining element (3) comprises an abutment face (3f) against which a corresponding hook element of the trolley abuts upon movement of the wall element towards the position of concerned end. Being substantially connected and at an angle to the abutment face (3f), each retaining leg (3b) comprises a retaining face (3g) behind which, when the wall element is in the position end 10 corresponding, the corresponding hook element will hang. The retaining legs (3b) of the illustrated door stop (1) are made with an elastic nature, such that they exert, during the abutment of a hook element of the rolling carriage against the abutment face (3f) or against the retaining face (3g), an opposing elastic force, which attempts to prevent the hook member from moving from the abutment face side (3f) to the side of the retaining face (3g) or vice versa. When the force is sufficient, this opposing elastic force is overcome during the abutment of the hook member against the abutment face (3f), the hook member thus moving towards the side of the retaining face (3g). . The wall element is thus brought and maintained in the corresponding end position. Conversely, when sufficient force is exerted on the wall member to move the wall member out of its end position, this resilient biasing force may be overcome upon abutment of the hook member against the retaining face (3g), the hook member thus moving towards the side of the abutment face (3f) and the wall member being disengaged from the end position.
